The significance of quality inspection lies in conformity evaluation through observation and judgment, and appropriate combination of measurement and test. (1) For products, it refers to the technical inspection activities of observing raw materials, intermediate products and finished products as appropriate according to product standards or inspection regulations, and comparing all the obtained characteristic values to determine whether each item or batch of products is qualified or unqualified.

(2) Quality inspection is to observe one or more quality characteristics of products. Technical inspection activities of measurement and testing, and compare the results with the specified quality requirements to determine the qualification of each quality characteristic.

2。 Basic Points of Quality Inspection (1) In order to meet customer requirements or expected use requirements and mandatory provisions of laws and regulations, the technical performance of a product must be evaluated.

Safety performance, interchangeability, environmental and personal safety, health impact and other requirements, these provisions constitute the corresponding quality characteristics of products. Different products will have different quality characteristics, and the same product will have different quality characteristics for different purposes.

(2) The requirements for product quality characteristics are generally translated into specific technical requirements, which are clearly stipulated in product technical standards (national standards, industry standards and enterprise standards) and other related product design drawings, operation documents or inspection procedures, and become the technical basis for quality inspection and the basis for comparing inspection results after inspection. Through comparison, it is determined whether each quality characteristic tested meets the requirements specified in standards and documents.

Product suitability is an important quality characteristic. (3) Product quality characteristics are formed in the process of product realization, which are determined by the quality of raw materials and parts (such as parts) of the product, and are closely related to the professional technology, personnel level, equipment capacity and even environmental conditions in the process of product realization.

Therefore, it is necessary not only to train the operators (operators) in the process, but also to be qualified for posts, verify the equipment capacity, monitor the environment, and clarify the operation and process methods. Monitor operation and process parameters if necessary.

But also the quality inspection of products to determine the quality of products. (4) Quality inspection is to observe, measure and test one or more quality characteristics of products through physical, chemical and other scientific and technological means and methods to obtain objective evidence to confirm the quality of products.

Therefore, it is necessary to have appropriate detection means (including various measuring instruments, meters, test equipment, etc.). ) and effectively control them to maintain the accuracy, precision and consistency required for detection. (5) According to the product technical standards, compare the quality inspection results with relevant product drawings, process (process) documents or inspection procedures to determine whether all quality characteristics are qualified (in line), so as to judge the quality of single (item) crystal production or batch products.

(6) Quality inspection shall provide correct and reliable basis for judging the conformity and applicability of product quality and making important decisions on product quality, and ensure the correctness and accuracy of product quality inspection results. 3。

The main function of quality inspection (1) Identification function According to the provisions of technical standards, product drawings, operation (process) regulations or order contracts and technical agreements, the corresponding inspection and inspection methods are adopted to observe, test and measure the quality characteristics of products to judge whether the product quality meets the specified requirements. This is the identification function of quality inspection. (2) The function of "gatekeeper" provides "entrance" for nonconforming products found through identification, and fails to deliver the intended use.

(3) Preventive function ① Play a preventive role through the determination of process (working procedure) capability and the use of control charts; (2) Through the first inspection and inspection of working procedure (working procedure), it plays a preventive role; ③ preventive action in a broad sense. (4) Reporting function In order to enable relevant management departments to grasp the quality status in the process of product realization, evaluate and analyze the effectiveness of quality control, summarize, sort out and analyze the data and information obtained from inspection, and then write a report, which provides important information and basis for quality control, quality improvement, quality assessment and quality supervision and management to make quality decisions.

4。 Quality inspection step (1) inspection preparation.

Be familiar with the specified requirements, select inspection methods and formulate inspection specifications. In the preparation stage of inspection, if necessary, the inspectors should be trained and assessed with relevant knowledge and skills to confirm whether they can meet the needs of inspection work.

(2) obtaining a test sample. The sample is the object of detection, and the quality characteristics objectively exist in the sample. After excluding the influence of other factors, it can be said that the sample objectively determines the test results.

There are two main ways to obtain samples: one is to send samples, and the other is to sample. (3) Samples and sample preparation.

(4) measurement or testing. According to the established inspection method and scheme, the product quality characteristics are observed, measured and tested quantitatively or qualitatively, and the required values and results are obtained.

Before and after the measurement and test, the inspector shall confirm that the samples of the inspection instruments and equipment and the inspected items are in a normal state, and ensure the correctness and validity of the measurement and test data. (5) Record and description.

Measuring conditions, measured values and observed technical conditions are recorded or described in standardized forms and requirements, and kept as objective quality evidence. (6) Comparative judgment.

Full-time personnel will compare the inspection results with the specified requirements to determine whether all quality characteristics meet the specified requirements, so as to determine whether the inspected products are qualified. (7) Confirmation and disposal.

Relevant inspectors shall sign the inspection records and judgment results for confirmation. Whether the disposal product (single piece or batch) can be "received" or "released".

5。 Conceptual verification of product verification refers to confirming that the specified requirements have been met by providing objective evidence.

This is a management inspection activity. 6。

Surveillance is meaningful.

2. What is the common sense of the medical examination project?

Three categories

1. The physical examination items of the clinical physical examination department require doctors to have rich clinical experience.

2. The physical examination items of the instrument physical examination department mainly rely on equipment, and technicians assist doctors to detect their physical condition through equipment.

3. The physical examination items of the laboratory physical examination department are mainly blood and urine, and then laboratory tests are carried out.

Detailed division and detailed content, the clinical significance is as follows: general examination, internal medicine, surgery, ophthalmology, otolaryngology, anorectal department, gynecological routine and other clinical projects.

With simple instruments, we can understand the basic situation of the body through physical examination such as on-site palpation.

Bleed

Draw blood (for laboratory examination)

Take a blood sample.

X-ray examination

Through chest X-ray fluoroscopy, the diseases that can be screened out include tuberculosis, lung tumor, pleural effusion, pneumothorax, bronchiectasis, tracheal dilatation, ventricular hypertrophy, aortic arch protrusion, scoliosis and the diagnosis of chest bone diseases. If the frontal chest X-ray examination is normal, but there is a long-term cough with bloodshot sputum, it is necessary to add a lateral chest X-ray examination.

bone density

People's bone mineral density reaches its peak around the age of 30, and then the bone is lost year by year, leading to the looseness and fragility of bone structure, and gradually "osteoporosis" appears. Therefore, it is best for normal people to have a screening every year after the age of 30.

Common subitem detection

stomach

Imported capsule endoscope

It is called "Intelligent Capsule Gastrointestinal Endoscope System" and "Medical Wireless Endoscope". Capsule endoscopy has the advantages of convenient examination, no trauma, no lead, no pain, no cross infection and no influence on the normal work of patients. It broadens the vision of digestive tract examination, overcomes the shortcomings of traditional insertion endoscope, such as poor tolerance, inapplicability to the elderly, infirmity and critical illness, and can be used as the first choice for the diagnosis of digestive tract diseases, especially small intestine diseases.

abdomen

Check whether there are lesions in gallbladder, liver, pancreas, spleen and kidney. It mainly examines eight parts, including liver, intrahepatic bile duct, common bile duct, gallbladder, kidney, hepatic portal vein, pancreas, spleen and others. Detect fatty liver, liver cirrhosis, hepatolithiasis, unexplained abdominal pain and other diseases.

prostate

Prostatic hyperplasia, prostatitis, prostate cancer, prostate cyst, prostate abscess, prostate tuberculosis, prostate calculus, etc.

electrocardiogram

Electrocardiogram (ECG) is used to track the potential changes related to heartbeat, so as to judge whether there are abnormal conditions such as atrial or ventricular hypertrophy, myocardial infarction, irregular pulse, pericarditis and systemic diseases.

Five items of internal medicine

(heart, lung, liver, spleen, nervous system, etc. ) exclude medical diseases or find signs of medical diseases through physical examination.

3. What are the basic points of quality inspection?

(1) In order to meet the customer's requirements or expected use requirements and the mandatory provisions of laws and regulations, the product must specify its technical performance, safety performance, interchangeability and the degree of influence on the environment, personal safety and health, which constitute the requirements for the corresponding quality characteristics of the product.

Different products will have different quality characteristics, and the same product will have different quality characteristics for different purposes. (2) The requirements for product quality characteristics are generally translated into specific technical requirements, which are clearly stipulated in product technical standards (national standards, industry standards and enterprise standards) and other related product design drawings, operation documents or inspection procedures, and become the technical basis for quality inspection and the basis for comparing inspection results after inspection.

By comparison, it is determined whether the characteristics of each inspection meet the requirements specified in standards and documents. (3) Product quality characteristics are formed in the process of product realization, which are determined by the quality of raw materials and parts (such as parts) of the product, and are closely related to the professional technology, personnel level, equipment capacity and even environmental conditions in the process of product realization.

Therefore, it is necessary not only to train operators in the process, but also to carry out post qualification certification, verify equipment capacity, monitor the environment and define the operation.

4. Fixture knowledge

I helped you find some knowledge about checking fixture purchase on the internet, hoping it will help you.

The design and manufacture of comprehensive testing tools and precision measuring tools need very professional knowledge, but the hard indicator in the eyes of buyers is generally only price. According to the characteristics of the industry, Haoyuan Technology Co., Ltd. gives users some tips to help them buy products with high quality and first-class design:

1. Measurement and testing is a highly technical job, especially when developing such tools. We will advise the purchaser to withdraw from the negotiation and hope that the user can communicate with us directly.

2. Once customers agree with us, we will communicate with users many times. After confirming or signing the contract, we will provide design drawings or more detailed plans to the customers for confirmation, and then start processing and manufacturing after there is no problem.

3. Because the products we design and manufacture have been carefully inspected, there is basically no phenomenon of repair and retreat. At the same time, after the design and processing of our products are completed, customers will be advised to find a third-party measurement and monitoring unit in the provincial and ministerial quality inspection departments to conduct third-party testing on the products we designed and manufactured.

4. In Chinese mainland, companies that can do a good job in precision measurement and testing are basically old state-owned enterprises, such as military/railway/heavy equipment manufacturing. Because this industry places too much emphasis on accumulation, many high-precision detection tools can't be machined at all. In the machinery industry, the worst and the best are handmade. The latter kind of handwork is a manifestation of exquisite craftsmanship, while the former is shoddy.

5. All the processing and manufacturing units that win customers by low prices are basically small and extensive enterprises with poor efficiency, while those who blindly pursue low prices are often non-technical personnel or labor-intensive enterprises that occupy the market by low-priced products themselves.

In order to avoid the problems described by the landlord, the best way is to let the buyer go away and let the user go by himself until everything is done.

6. How to become a qualified quality engineer?

The biggest role of quality engineers is to make the company's production in a controllable state, that is, steady state, through the use of seven tools, which is the core idea of your work.

Quality management is not the traditional five tools, but now seven tools, including causality diagram, histogram, Pareto diagram, questionnaire, hierarchy method, scatter diagram and control chart. If in reality, the control chart is the tool that can directly control the early warning of process stability, most other tools are used to find out the reasons afterwards. Then the questionnaire is also the most commonly used tool in factories, which is concise and clear, and the effect is also very practical. But when it comes to practical application, you have to understand the theory first, because the application of these tools is not very difficult, mainly the understanding of the theory and the supplement of a lot of statistical knowledge.

The application of PDCA continuous improvement is relatively simple. To sum up, it is a cyclical process of constantly discovering and solving problems, which is not as profound as you think.

As for the 8D report, I haven't heard of it before, but after a brief search, I found that it is only a quality improvement activity that people from different departments of the enterprise participate in. It can be a specific application of PDCA, similar to QC activity group, but the scope of the object is a little small, which requires that the problem object can be greatly changed, so it is important and difficult to choose the problem to improve.

Quality engineer is not a system engineer, but you can participate, because internal audit is not that difficult, but you must understand your quality system; It's better to say upstairs to fill out the form. This is only a small part of the scope covered by quality engineers.

Please respect the efforts and labor of the respondents. If you are satisfied with my answer, please adopt it as the best answer.

7. How to do quality inspection?

Quality is the foundation of enterprise's survival and development. A successful enterprise must have a strong sense of quality and the spirit of continuous improvement and innovation.

1 A good quality inspection is to urge production to adopt correct or improved methods under the relative standards or requirements, so that lazy people can make continuous progress in management and technology, thus improving production level and enterprise efficiency. As a quality inspector, you must have good psychological quality and excellent professional knowledge.

In addition to being familiar with the requirements of users and the latest changes in the product market, we should also be familiar with the performance and efficacy of products. To be a good quality inspector, you should have the ability of data analysis and feedback the changes of product quality to the production and boss. There will inevitably be contradictions between quality inspection and production. Quality inspection is from the customer's perspective, but quality inspection is to maintain the company's image and create benefits for the company.
